There are tons of recipes on this site. Almost any recipe can be converted to wild game if you use a mix deer and pork say a 60/40 or 50/50 ratio. Deer is very lean so you need the fat content.
If you don't already own this book I would highly suggest it. It is considered to be the holy grail of sausage making. Most importantly is has amazing write up on the use cures, processing the meat, smoker times and temps. ect

Of all those ready to mix kits I have tried, the ones sold at Halford's Hides are the only ones that generally get a good reception. Personally I like the honey garlic and summer sausages myself with a little tweeking.
