You can buy "bacon bits" in supermarkets (usually in or near the spice section). The last bottle I bought I tasted one and threw them out. I used to like these, but this lot tasted revolting - you may like them, though. They are a vegetarian item, so it's OK to use them if you are vegetarian or vegan (I think they are vegan, but it may be wise to check the ingredients). I think I would probably experiment with liquid smoke if you wanted that taste. See how you go, anyway.
