Whisk worchestire sauce, tamari sauce, paprika, molasses, black pepper, red pepper flakes, garlic powder, and onion powder together in a bowl. Add sliced meat to a bowl and turn to coat completely. Cover the bowl with plastic wrap and marinate in the refrigerator for up to 3 hours or overnight.

Lay seasoned meat on the trays of a dehydrator and dehydrate according to the instructions on your dehydrator (about 4 hours at 160-degrees) You can use the oven if you don't have a dehydrator. Preheat oven to 175 degrees. Line a baking sheet with aluminum foil and place a wire rack over the foil. Place meat on paper towels to dry off excess marinade. Discard the remaining marinade. Arrange meat slices in a single layer on the prepared wire rack on the baking sheet.

Bake meat in the preheated oven until dry and leathery about 3 to 4 hours. Let cool before enjoying.
