:wasalam:
When you recite an Ayah of Sajdah, turn towards Qiblah, say Allahu Akbar and perform a Sajdah, and rise up saying Allahu Akbar.
Read the following Du'a in Sajdah:
"سجد وجهي للذي خلقه وشق سمعه وبصره بحوله وقوته فتبارك الله أحسن الخالقين".
"Sajada wajhiya lilladhi khalaqahu wa shaqqa sam'ahu wa basarahu bi Hawlihi wa quwwatihi, fa tabaarak-Allahu aHsanul khaliqeen".
(I have prostrated my face to the One Who created it and brought forth its hearing and seeing by His Might and Power. Blessed be Allah the Best of Creators).
