I’d recommend seitan bacon over tempeh bacon. It’s made from gluten (wheat protein) that they make a dough with and fill with fat, seasoning, msg etc. to make it taste like bacon, and it fries really crispy like bacon. Upton is a brand I usually buy but I get it at a vegetarian grocery so not sure if it’s widely available, but any vegetarian bacon where the first ingredient is wheat gluten would be the same.
