depends on what it's in: if I want something salty and smokey (say, to add to pea soup), then I use chipotles in adobo. If I want something crispy (like in a salad), then I use seasoned croutons or a veg-based substitute. If I want something fatty, I'll add extra oil to what I'm cooking. Just think about what you like about bacon and focus on all the different ways you can find the same flavors.
PS - heads up if you've never had it, tempeh needs to cooked and flavored to taste like bacon (it's not even close on it's own, it's more like fermented tofu).
