The Entrance Song is sung as the Priest approaches the altar. When you hear the bell ring, stand and face the procession. Make the Sign of the Cross by touching your forehead, heart, left shoulder and right shoulder, then put your palms together in prayer as the priest says:
Priest:  In the name of the Father, and of the Son, and of the Holy Spirit. 
People: Amen.

Omitted on Ash Wednesday.

Brothers and sisters, let us acknowledge our sins, and so prepare ourselves to celebrate the sacred mysteries.
I confess to almighty God and to you, my brothers and sisters, that I have greatly sinned, in my thoughts and in my words, in what I have done and in what I have failed to do, (strike breast 3x) through my fault, through my fault, through my most grievous fault; therefore I ask blessed Mary ever-Virgin, all the Angels and Saints, and you, my brothers and sisters, to pray for me to the Lord our God.

Blessed are you, Lord God of all creation, for through your goodness we have received the bread we offer you: fruit of the earth and work of human hands, it will become for us the bread of life.
Blessed be God for ever.
Blessed are you, Lord God of all creation, for through your goodness we have received the wine we offer you: fruit of the vine and work of human hands, it will become our spiritual drink. 
Blessed be God for ever. 
...that my sacrifice and yours may be acceptable to God, the almighty Father.
May the Lord accept the sacrifice at your hands for the praise and glory of his name, for our good and the good of all his holy church.

If you want to make a worship offering to God, you may give here.

Pray, brethren, that my sacrifice and your may be acceptable to God, the almighty Father.
May the Lord accept the sacrifice at your hands. For the praise and glory of his name. For our good and the good of all your Church.

The Lord be with you.
And with your spirit.
Lift up your hearts.
We lift them up to the Lord.
Let us give thanks to the Lord our God.
It is right and just.

This is used in Ordinary Time. The Priest may choose a different Preface.
It is truly right and just, our duty and our salvation, always, and everywhere to give you thanks, Lord, holy father, Almighty, and eternal God, through Christ, our Lord. For out of compassion for the waywardness that is ours, he humbled himself, and was born of the Virgin; by the passion of the cross, he freed us from unending death, and by rising from the dead, he gave us eternal life. And so, with angels and archangels, with thrones and dominions, and with all the hosts and powers of heaven, we sing the hymn of your glory, as without, end we acclaim:

Holy, Holy, Holy Lord, God of hosts. Heaven and earth are full of your glory. Hosanna in the highest. Blessed is he who comes in the name of the Lord. Hosanna in the highest.

OR

Sanctus, Sanctus, Sanctus, Dominus Deus Sabaoth. Pleni sunt caeli et terra gloria tua. Hosanna in excelsis. Benedictus qui venit in nomine Domini. Hosanna in excelsis.

The Priest has over ten different texts to choose from. During this prayer, he asks the Holy Spirit to transorm the bread and wine so that they become the Body and Blood of Jesus Christ. The Priest then says the words of Jesus:

"Take this, all of you, and eat of it, for this is my Body, which will be given up for you."

As the bells rings during the consecration of the Bread, bow your head and pray silently, My Lord and my God.

"Take this, all of you, and drink from it, for this is the chalice of my Blood, the Blood of the new and eternal covenant, which will be poured out for you and for many for the forgivenes of sins. Do this in memory of Me."

As the bells rings during the consecration of the Blood, bow your head and pray silently, My Lord and my God.

After the Body and Blood of Christ are raised, we say or sing and acclamation. The most common is:

The mystery of faith.

We proclaim your Death, O Lord, and profess your Resurrection until you come again. 

During the rest of the Eucharistic Prayer, we pray for the whole Church.  At the end, the Priest says:

Through him, and with him, and in him, O God, almighty Father, in the unity of the Hoy Spirit, all glory and honor is yours, for ever and ever. 
Amen.

At the Savior's command and formed by divine teaching, we dare to say:
Our Father, who art in heaven, hallowed by they name; they kingdom come, they will be done on earth as it is in heaven. Give us this day our daily bread, and forgive us our trespasses, as we forgive those who trespass against us; and lead us not into temptation, but deliver us from evil. 

Deliver us, Lord, we pray, from every evil, graciously grant peace in our days, that, by the help of your mercy, we may be always free from sin and safe from all distress, as we await the blessed hope and the coming of our Savior, Jesus Christ.
For the kingdom, the power and the glory are yours now and for ever.

Lord Jesus Christ, who said to your Apostles: Peace I leave you, my peace I give you, look not on our sins, but on the faith of your Church, and graciously grant her peace and unity in accordance with your will. Who live and reign for ever and ever.
Amen.
The peace of the Lord be with you always.
And with your spirit. 
Let us offer each other the sign of peace.

Exchange a sign of peace and say:
Christ's peace be with you.

Then the Priest take the host, breaks it over the paten, and places a small piece in the chalice. Meanwhile, the following is sung or said:

Lamb of God, you take away the sins of the world, have mercy on us.
Lamb of God, you take away the sins of the world, have mercy on us.
Lamb of God, you take away the sins of the world, grant us peace.

OR

Agnus Dei, qui tollis peccata mundi, miserere nobis. 

Agnus Dei, qui tollis peccata mundi, dona nobis pacem.

Kneel.
