What are you used to in C/C++ land?

Apart from automating the code deployment to the target, I'm not sure
there's a lot more you can do. Erlang gives you great remote debugging
and code reloading, but that doesn't seem to be your problem.

If you wanted to keep the target Erlang VM running throughout your
development, you could run Mochiweb's "reloader" module to watch for
local changes to beam files and forcefully reload them. You'd still
need to push the compiled files over -- but that could be a part of
your make file (e.g. extend the compile target to compile and
ftp/rsync/etc to your target device).
