Soaking in soy sauce or teriyaki sauce is a favorite. A mixture of salt, pepper, oregano, marjoram, basil and thyme is tasty. Many seasonings work well. It is a personal preference. Dry seasoning mixtures need to be pounded into the meat for best results.
Many people enjoy jerky with a lot of pepper.
You will need to experiment to find your favorites. After the meat is seasoned, spread the meat evenly on wire racks in the oven. Try not to have the meat pieces touch each other. You can use metal racks other than the oven racks with a cookie sheet underneath to make cleanup much faster. Also a nonstick spray lightly sprayed on the racks makes for easier cleanup.
