You'll need to create a ipv6ip tunnel; the best place being between your ASA and router. This can either be server or an inexpensive Cisco 1841 (for example) peering with a tunnel broker such as Hurricane Electric.
Run OSPF between the router and you ASA. If using a linux server to for your tunnel, then you'll need to configure something like quagga to run the OSPF process.
This will give you a IPv6 lab environment.
If some of your kit then needs to connect to IPv4 external hosts then you will need to configure NAT64. If you chose the linux server option above, using tayga seems to be the popular option currently.
