Only a (relatively) small number of units have awakened skills that can only be used once per sortie. Of those a number specifically note that they change to the normal version of the skill after use. The ones that specify a limited number of uses and no not state that they change back to the unawakened skill will leave the unit without a skill after all the uses are used up.

Awakened skills do not have levels. You need the skill at max level before you can awaken it, but there is no leveling it after. You can redo the cost of awakening a skill to change it back as well, and from my understanding it changes back into a max level version of the skill.
