I highly recommend the High Mountain Jerky seasoning. You can't mix your own for the $7.99 they want for the kit at Sportsmans.
Also, it is much easier to slice if the meat is soft frozen.
This simple internet marinade has proven delicious with moose (cheap slicer and cheap dehydrator- about 3hrs on high after 3 to 6 hours of marinating). I try to cross cut against the grain and like the drying/shrinkage results of a 1/4 inch slice. Maybe a bit smaller.
2/3 cup worcestershire sauce
