As far as I know, there is no general way to do this.
It's possible to create a bootable image that is also an valid ISO.
But the mechanism used by the firmware to boot USB storage devices is
quite different from the mechanism used to boot from a cdrom.
Still, it's possible you may be able to solve your particular problem.
A good place to start would be the syslinux package. It provides
support for booting systems from a variety of media, including DOS FAT
filesystems, Linux ext2/3/4 filesystems, PXE network boots, and ISO
9660 cdroms.
