01 - Whisk olive oil, soy sauce or tamari, maple syrup, apple cider vinegar, vanilla extract, garlic, thyme, rosemary, parsley, black pepper, and salt in a shallow dish to create the marinade.
02 - Place tempeh steaks in the marinade, turning to coat all sides evenly. Cover and refrigerate for at least 30 minutes or up to 2 hours for enhanced flavor.
03 - Warm a large non-stick skillet over medium heat in preparation for cooking.
04 - Add marinated tempeh steaks to the skillet, reserving leftover marinade. Cook for 4 to 5 minutes per side until golden brown and lightly caramelized, basting occasionally with reserved marinade.
05 - Serve the tempeh steaks hot, garnished with fresh herbs and lemon wedges as desired.
