In a bowl, mix flour and salt. Cut in vegan butter until mixture resembles coarse crumbs.
Add ice water, 1 tablespoon at a time, until dough forms. Wrap in plastic and chill for 30 minutes.
Roll out dough and fit into a tart pan. Trim excess dough.
In another bowl, mix peaches, sugar, cornstarch, vanilla, and cinnamon.
