These are the ones in the agpeya at my church:
A PRAYER BEFORE COMMUNION
(Of St. John Chrysostom)
I believe, O Lord, and I confess that Thou art truly Christ, the Son of the Living God, Who came into the world to save sinners, of whom I am chief. And I believe that this is truly Thine own immaculate Body and that this is truly Thine own precious Blood. Wherefore I pray Thee, have mercy upon me and forgive my transgressions both voluntary and involuntary, of word and of deed, of knowledge and of ignorance; and make me worthy to partake without condemnation of Thine immaculate Mysteries, unto remission of my sins and unto life everlasting. Amen.
A PRAYER AFTER COMMUNION
(Of Saint Basil the Great)
O Lord, Christ our God, King of the ages, and Creator of all, I thank Thee for all the good things which Thou hast bestowed upon me, and for this communion of Thine immaculate and life-giving Mysteries. Therefore I entreat Thee, O Good One Who lovest mankind: keep me in Thy tabernacle and under the shadow of Thy wings; and grant that, with a pure conscience, even unto my last breath, I may worthily partake of Thine holy Things, unto the remission of my sins and unto life eternal. For Thou art the Bread of Life, the Fountain of all holiness, the Giver of good things; and unto Thee we ascribe glory, O Father, Son and Holy Spirit, now and ever, and unto the age of ages. Amen.
