Make the marinade by combining the soy sauce, maple syrup, oil, liquid smoke, balsamic vinegar, cumin and garlic powder.
Toss the sliced tempeh strips in marinade to fully coat. Arrange strips in a single layer in shallow baking dish so every piece is in the marinade, and refrigerate from at least 15 minutes.
Once tempeh has been left in marinade for a sufficient amount of time, heat oil in large frying pan over medium heat. Add tempeh strips and cook in the pan for about 3 minutes on each side, or until edges are brown. Use the leftover marinade to deglaze pan.
Arrange tempeh bacon in tortilla with greens, tomatoes and vegan mayo. Enjoy!
