I'm trying to find all of the dialogue (specifically the audio) M'aiq has in the game, but for some reason I can't find any associated with his character. Everything I have found is just generic stuff that has nothing to do with him.

I've gone through this process before with other NPCs and never run into this problem. Does anyone know where the files are located?

I'm also in a hurry to find them, so getting help soon would be great!

According to the CK, his voice type is Male Khajit. So you have to extract the Voice.bsa and unfuz everything, go to the Male Khajit folder, and start searching.
It can be daunting since there's hundreds of lines there, but it's in there. Sometimes the name of the file might itself be a clue.

Have you tried searching the quests for "maiq*dialogue"?
