Stuff comes up when I google "moose sausage recipe".
I haven't tried it myself yet. I am a trained Chef of over a decade though, so I'd just wing it myself.
I'd definitely add fat. Pork fat. Maybe even mix it a bit with pork meat.
Then just add spices and seasonings, herbs.
(Fennel seed. Thyme. Rosemary. Caraway. Sage. The combinations are endless. Or even purchase a spice blend and do that. No shame in that.)
Cook some up on the side, see if it needs any fixing before sausaging away. Then, sausage away.
I'd think about smoking them too, I would.
