Mix the soy sauce, canola oil, honey, and lime juice in a large bowl until well combined
Add minced garlic, ground cumin, smoked paprika, black pepper, and cayenne pepper. Mix well and make sure there are no lumps or undissolved ingredients
Place the tri-tip into a large resealable bag and pour the marinade over the top. Seal the bag and massage the marinade into the steaks until all pieces are evenly coated
Place the tri-tip in the fridge for at least 4 hours or overnight, flipping the bag occasionally to ensure that the meat is well coated
When ready to cook, remove the meat from the marinade and discard any remaining marinade
Grill or roast the tri-tip to your desired temperature for doneness (preferably medium rare), then slice and serve
