Eco-Libre's website has a map of vegan intentional communities in Ecuador:

The map shows 11 communities: 7 strictly-vegan plus 4 vegetarian (or mostly-vegetarian) communities. Some of them are clustered together, so it's hard to see without zooming-in, but the link above has an interactive map and lists all the communities with links to their websites for more info.
Most of them are located in the Amazon and are focused on reforestation or conservation of some kind. Many are raw vegan or high-raw or fruit-based (much of the volunteer work appears to be dedicated to growing fruit tree forests).
