Combine soy sauce, maple syrup, apple cider vinegar, minced garlic, black pepper, smoked paprika, onion powder, and cayenne pepper in a bowl to create the marinade.
Place venison slices in a large ziplock bag and pour the marinade over them. Seal and massage the marinade into the meat. Refrigerate for at least 4 hours, preferably overnight.
Preheat your smoker to 160°F (71°C). Arrange the marinated venison slices on the smoker racks, ensuring they don't overlap.
Smoke for about 4-6 hours, or until the jerky is dry but still pliable.
Let the jerky cool before storing it in an airtight container.
