So an he.net tunnel has a /64 used as a point-to-point network which is what runs on the IPv4 tunnel, and either a single /64 that you route for your internal subnet, or a /48 which allows you to carve out 65535 subnets of /64 each, equivalent addressing to an IPv4 /16 where each address is NATting for an entire network itself.
So pick the first /64 subnet inside your /48 allocated to you and route that internally and set that up in your router advertisement daemon.
For example if your point-to-point is
2001:470:AAAA:1234::1/64 (HE.net) -- 2001:470:AAAA:1234::2/64 (your router)
and your routed subnets are out of 2001:470:BBBB:1234::/48
2001:470:BBBB:1234::/64
2001:470:BBBB:1235::/64
...
Then you'd have say 2001:470:BBBB:1234::1/64 on one router interface and advertise 2001:470:BBBB:1234::/64
