First say the Trisagion Prayers, then the following prayer:
O Christ our God, who at this hour didst stretch our thy loving arms upon the Cross that all men might be gathered unto thee, help us and save us who cry out unto thee: Glory to thee, O Lord.
Then add your private devotions and intercessions, and conclude with this prayer:
Through the prayers of our holy Fathers, Lord Jesus Christ our God, have mercy upon us and save us. Amen.
