To personalize your message, mention:

A favorite childhood memory
Something you admire about her
A time she supported you
An accomplishment you are proud of
A shared joke or family tradition
Something you hope she achieves in the coming year

A specific detail will usually make your message feel more genuine than simply using a long collection of generic birthday phrases.
