You can do two things:

1) Starting with an existing image, do the following:

mount /path/to/existing.img /mnt
mount --bind /dev /mnt/dev
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt

Then create a .repo file in /etc/yum.repos.d/ for the repository you
want to include if it isn't already there, and do

yum update
yum install <extra packages you want to install>

2) Starting from scratch, you can do:

yum --installroot=/path/to/new/rootfs/subdirectory \
  glibc filesystem coreutils initscripts \
  <plus any other packages you want in your image>

Adjust configuration files for console and network to suit
your intended device and add any binary blobs you might need
for it. Also add any booting related configuration (e.g.
uboot config if appropriate to your device).

Prepare an image file of the suitable size:
dd if=/dev/zero of=rootfs.img bs=1M count=0 seek=4095
mkfs.ext4 rootfs.img
mount -o loop rootfs.img /mnt
tar -C /path/to/new/rootfs/subdirectory -cf - | tar -C /mnt -xf -
umount /mnt

You can then dd rootfs.img to your boot media.
