Another great recipe from How It All Vegan
1 lb extra-firm tofu
1/2 cup braggs or soy sauce
3/4 tbsp liquid smoke
1/8 cup water
1 tbsp onion powder
1 tsp garlic powder or 1 clove garlic, crushed
1 tbsp pepper
1 tsp organic sugar
Cut the drained tofu into long narrow strips (about 1/4 inch thickness). They may look big, but they will shrink during baking. In a small bowl, whisk together th Braggs, liquid smoke, water, onion powder, garlic, pepper, and sugar. Place the tofu strips in a shallow baking pan or on a cookie sheet and pour the marinade over them. Let them marinat for several hours or overnight for best results.
Cook the tofu in a food dehydrator (follow directions) or bake in the oven for about 4-6 hours at 200F. Turn the tofu over once every hour so it bakes evenly. Continue until the texture is very chewy, but not crispy. Tofu jerky will keep indefinitely. Store in a container with a tight-fitting lid.
