I think you'll have to be clearer in your request, it seems like this information already incorporated on this wiki, at most lacking proper update. The current format includes a brief description of each power/ability and notable examples, which should mention the earliest appearance along with a reference to the episode. You can see this pattern in this paragraph in Cordelia's article:


 * Visions: Originally a normal human, Cordelia began receiving prophetic visions from the Powers That Be.[41]  The visions usually consisted of ambiguous imagery of forthcoming attacks on innocents or various demonic disasters. Cordelia used this imagery to help Angel prevent them from happening.

Still, you may notice not all articles include this section, and, even so, there's still room for improvement, as you know this is a collaborative encyclopedia.
