If I add a second Internet feed and can't run BGP, how do I tell my
network to send traffic out via the new router?

BGP is just your EGP. All you need to do to make sure traffic goes
out both links is ensure that whatever routing protocol is running
between your network/core and the internet routers has equal costs or
a preferred metric for whatever internet pipe you wish to use. Also
make sure that the second ISP router does not have a better default
route out the other internet router, and is sending traffic out that
it receives from the core. All of this can be done with show ip route
0.0.0.0 commands.

Balancing internet traffic back in is a completely different story as
I'm sure you are aware......
