Cut Tempeh into whatever shape you desire. I like to turn the block of tempeh on its side first and cut horizontally through the tempeh so it's thinner. This will result in a crisper tempeh.
Combine all marinade ingredients into a mixing bowl and gently whisk with a fork.
Add tempeh and ensure all sides are coated with the marinade.
Bake for 20-25 minutes at 160° C
