Marinade: In a wide, shallow bowl, stir together all ingredients except the tempeh.
Tempeh: Slice tempeh into thin (¼ inch thick) strips. Transfer tempeh to the bowl with the marinade and cover each with the mixture. Let soak for at least 30 minutes (up to 24 hours). Reserve marinade.
Bake: Preheat oven to 350°F (176°C). Place tempeh in a single layer on a parchment-lined baking sheet. Bake for 15 minutes, then flip each tempeh bacon strip over, brush with remaining marinade, and cook for another 15 minutes, or until crisp at the edges.
