I was searching for a while for a slow cooker cookbook for vegans and finally found this one. The recipes are really good. There is a lot of seitan recipes, which is one of my favorite proteins.

If you are in a hurry many could be cooked in a covered pot but the long times in the slow cooker means you could put them on in the morning and they will be ready at night.

In some of the recipes I did find it a bit annoying that she wanted you to do so many things before adding the food ( grilling or browning or marinading etc) but I cant argue that the food tastes great.

A word of caution. Many of the recipes call for a trivet for your slow cooker to sort of steam the food. Mine did not come with this and I have no idea where to get it!
