As for the marinade you could add many other seasonings to your liking. Below is a base marinade that I start with.

Ingredients:
1/2 block of extra firm tofu
4 Tbsp tamari
1 tsp liquid smoke
1 tsp garlic powder
1/2 tsp paprika
Several cranks of Black pepper

Directions:
Mix all ingredients except tofu in a bowl.
Press the tofu dry being careful not to damage the integrity of the block. I cut the half block in half again and lightly press them individually between paper towels.
Cut the tofu into thin slices.
Dip tofu strips in the marinade.
Place tofu strips on a parchment paper lined baking sheet.
Bake for 2.5 to 3 hours at 200 degrees.

After 3 hours in the oven.
