What about the Q&D way of

	# newfs /dev/da1

to initialize a new UFS file system (without slicing and/or
partitioning, no matter if MBR or GPT) and then simply try

	# mount -t ufs /dev/da1 /mnt

and check if it works?

Keep in mind you can - after you've verified this works -
use tunefs to optimize UFS for use on USB sticks (optimization
selection for speed or space, reserved space, and consider
mount options like async/noasync or atime/noatime, depending
on your intended use).

See "man newfs", "man tunefs" and "man mount" for details.
