From Vegetarian Times
1/3 cup maple syrup
1/3 cup brown rice syrup
1/3 cup tamari
2 tablespoons toasted sesame oil
1 clove garlic, minced
1 teaspoon red pepper flakes
1 teaspoon paprika
1/2 teaspoon minced fresh ginger
1/2 teaspoon chili powder
1/4 teaspoon cayenne pepper
2 pounds tempeh, sliced in half width-wise, each half cut into 4 triangles
Whisk together maple syrup, rice syrup, tamari, sesame oil, garlic, red pepper flakes, paprika, ginger, chili powder, cayenne pepper, and 2 tablespoons water in a glass baking dish. Arrange tempeh triangles in marinade, and turn to coat. Cover, and marinate in refrigerator 4 hours, or overnight, turning occasionally.
Preheat broiler. Line broiler pan with aluminum foil. Transfer tempeh pieces to broiler pan, and reserve marinade. Broil tempeh 3 minutes on each side, or until triangles are golden brown and heated through, brushing tops with reserved marinade when turned. Bring remaining marinade to a boil in saucepan. Serve tempeh triangles drizzled with sauce from marinade.
