Cut the tempeh into thin strips, about 1/8 to 1/4 inches thick.
In a small bowl, whisk together the 2 tablespoons olive oil, 2 1/2 tablespoons tamari, 3 teaspoons liquid smoke, 1 1/4 teaspoons black pepper, 1 1/2 teaspoons cumin and 2 pinches of cayenne.
Place the tempeh in a shallow dish and pour on the marinade. Turn the tempeh several times to make sure it is fully coated. Leave to marinate for around 10 minutes.
Heat a griddle or skillet. Add some olive oil and pan fry the tempeh on each side until browned (or until a bit charred, if you like it crispy!).
Remove to a plate to cool. If desired, season with sea salt and fresh ground pepper.
