How about a special journal or notebook for him to write in? There are many different types of notebooks, such as those with leather covers or with motivational quotes on the front. Another idea could be a nice pen or set of pens to use with the notebook. You could also include some writing prompts or exercises in the notebook to help inspire him. If he enjoys reading, you could also consider getting him a book on writing or a collection of essays from different writers. Finally, another thoughtful idea could be to create a custom writing kit with his favorite pens, pencils, erasers, and other writing tools neatly organized in a box or container.
Or you can get him a star map with an important date you share.
