If you haven't seen my review on vegan spam, check it out here. This vegan spam recipe is probably the one most commonly referred to on the internet. It's a combination of soybean flour, peanut butter, tomato juice and several other flavorings. I'll say it's definitely not a perfect substitute for Spam's soft and gelatinous texture, but the flavor is not bad. Because of the myriad of Asian recipes which call for Spam, it's not a bad idea to have the recipe under you sleeves.
