If you are asking about how to recite salawat (prayers for the prophet and his household), it is as follows:
[ALAHUMA SALLI ALA MOHAMMAD WA AALI MOHAMMED] , and it is recommended (mustahab) to follow it with saying [WA AJIL FARAJAHUM] which is prayers for imam Mahdi (PBUH).
If you are asking about reciting something else please clarify .
