Going for 'strace' is a common next step, to see where it might be
hanging. strace will show you the kernel calls. Just:

strace yum install whatever

Be warned, it can produce a lot of output. You can redirect that, though:
strace -o /tmp/yum.log yum install whatever

Based upon the log, you might find a network connection timing out
(e.g. a connect() connect) or a filesystem hanging (in open()), for
example.
