Prepare: Cut 8 ounces Tempeh into strips or chunks that are similar in size.
Mix the 1 tablespoon Soy Sauce, 1 tablespoon Olive Oil, 1/2 teaspoon Garlic Powder together in a small bowl.
Place the tempeh pieces into a shallow dish and pour the marinade over the tempeh and marinate at room temperature for 30 minutes.
Drain the marinade from the tempeh and place them on a preheated grill in a single layer. Cook for 2 to 3 minutes, brush with barbecue sauce and flip over. Brush with more sauce and cook for 2 to 3 minutes longer.
