Not sure why you're particularly looking to increase hp, when it'll obviously come naturally.
To quote a person that answered in a thread that I made on the same topic:

HP is something that comes as a neat bonus to ranking dmg skills. You shouldn't really focus on it at all, it will just come naturally eventually.
Besides, oblivion spam and restored gives a nice amount of HP.
You really shouldn't need to focus on hp skills. You're an elf, dex should be your focus, not hp.
