With German menus you get \mathbb with Alt+z k . the shortcuts are defined in the file "menus.bind". So have a look at your windows in the folder~:\Programme\LyX 1.6.7\Resources\bind\de and open menus.bind with a text editor.Sorry for being a bit insisting here. In my version Alt+z k means font-noun.
That is \mathbb. Just use the shortcut Alt+z k and you can see in LyX's View source window (menu View->View Source) that \mathbb is created.
