Is there a class ability, spell or other, that lets you share spells with your familiar?


Scenario:

I have a Wizard/Warlock with pact of the chain feature, who I have themed off He-Man. I love the idea of using Tenser’s Transformation to buff both he and his familiar up for combat. However, it has a range of self, which seems to really limit my options.

Anyone have a work around? I am willing to change my class or multi class as needed. (We stick to using the hardcover books, and not UA or 3rd party stuff)
