Start by checking /var/cache/yum to see if the RPMs for your most recently installed kernel are still there. If they are, use "rpm -ivh --oldpackage ..." to re-install, and that should re-populate /boot. If they're not in the cache, you'll need to manually download them from mirrors.centos.org and then proceed with rpm -i. I also suggest that you "yum install yum-utils" and use package-cleanup to manage your old kernel files from now on.
