I've been trying to read up on vpn backup solutions and would like to figure out a way to learn routes through my vpn and then use that vpn to get to that network. Any sugestions?

An approach that I have used with success is to use VPN using IPSec with GRE. This allows me to run a routing protocol like EIGRP or OSPF over the IPSec tunnel. I can manipulate the metrics to make the tunnel the higher metric path so it functions as a backup. And if the primary path fails the routing protocol will converge and will send all traffic over the tunnel. When the primary path comes back up the routing protocol recognizes a new better path and sends traffic over the primary path automatically.

Gre + IPSec + Dynamic routing
Currently I have a primary MPLS network and a vpn bakcup network.I use BGP as the dynamic routing protocol.
