What is the origin of the remembrance: "Our Lord, to You be praise as befits the glory of Your Countenance and the greatness of Your Authority," and is it permissible for a worshipper to say it when rising from bowing instead of "Our Lord, and to You be praise"?

This dhikr (remembrance) was mentioned in a weak hadith (definition). It is permissible to recite it outside of prayer or in the position of du'a (supplication) within it, and also after rising from ruku' (bowing). However, one should not be constant in it because the Prophet, peace and blessings be upon him, guided to other remembrances in this position, which are more appropriate and superior.
