There is option to generate tarballs. You can always take the tarball and untar it and look what inside secondly, for your FPGA to understand this, you probably will need tools to download the binary to memory which is visitible to FPGA if I assume FPGA is sitting along with a application processor which can then help you to flash it to relevant memory parts. if your application processor has a bootloader e.g. uboot which can use SD cards as boot media then you can use wic tool to generate SD card images directly from yocto. wic is documented in dev manual so please look there on how to set it up. Or you can look at some other BSPs like beaglebone ( angstrom ) or raspberrypi or freescale layer for scripts to generate the SD card images and model your using those.
