That should be rather easy, follow:
http://wiki.archlinux.org/index.php/LUKS

Basically:

$ cryptsetup -c aes-xts-plain -y -s 512 luksFormat /dev/sda3
$ cryptsetup luksOpen /dev/sda3 test
$ mkfs.ext3 /dev/mapper/test

I just tried to cp -rp the data away. There was no write to the fs at the time
I think.
