Would it be awkward if I call him "cuz" back?

He's your cousin so you can def call him cuz whenever you want! Doesn't matter how close you are he's still your cousin. Just say it and don't feel awkward about it. People say cuz even if its not rly their cousin. Cuz is a very popular nickname for most anyone so you Def have usage right to this nickname for him. plus it doesn't matter how far away family is or how often you talk. Family is family and distance doesn't change that. It's an unwritten bond. It's in your blood. Distance whatever don't change that.
