According to La Fourchette, which is a website where you can find all the restaurants in France, the only Vegan restaurant in the 5th arrondiss*m*nt of Paris is "Le Puits de LΓ©gumes".
I leave it to you to use La Fourchette to find others! Around the 5th, you have the 6th, the 4th and the 13th arrondiss*m*nts.

Happy-cow let's you find vegetarian, vegan and veg-friendly places in Paris and a lot more cities. It shows the results in a map (allowing some interesting options as choosing just those places that are currently open) and a list ordered by distance/rating/price or some other criteria.
It also allows you to post reviews, making it easier to choose when considering different options.
