Make your new songs (grids) and drag them into a new Playlist (File>New playlist).
Name the playlist.
Click on the playlist to make sure it is selected (check all your songs are in there);
Top right is the Share icon, Email the playlist to your iPad (if you have a song selected in song view, you can just Share>Song via email)

Is this enough information?
There are tutorials in the Help menu.
