You can use the tools provided here:
https://github.com/lxc/lxc-ci

To produce a custom templates, you will have to adapt some file in 
lxc-ci/templates and then run bin/build-image. I did it a lot before to 
get working Debian Jessie containers before lxc 1.1.5 arrived in 
jessie-backports. When you get the custom template and its rootfs, you 
can choose to force the cache to use them or to create a custom template 
server.
