I'm far from an expert, but here is the recipe I used for the batch I'm drying tonight:
1/4 cup soy sauce
2 cups worcestershire sauce
2 tablespoons liquid smoke
3 tablespoons pickling salt
3 tablespoons seasoning salt (lawrys)
1 tablespoon black pepper
1 tablespoon meat tenderizer
1 tablespoon garlic powder (not garlic salt)
1 tablespoon onion powder (not onion salt)
1 tablespoon paprika
Will easily marinade 2 lbs of meat (should cover 3 lbs)
I dip the sliced meat in the marinade so it's completely covered. Then put it in an air-tight container (or zip loc bag) and toss it in the fridge for a couple of days with any leftover marinade. Mix the meat up a time or two per day to make sure everything gets it's fair share of flavor.
Dry in an dehydrator or oven until well dried. Stop before it's cardboard, but not before most of the moisture is removed.
Store in an air tight container for a few weeks, or vacuum seal and freeze it for extended storage.
