You will need to already be a Vampire Lord and far enough along in the Dawnguard quest line where You can be turned into a Vampire Lord for the SECOND time by Serana. It does not matter which side your on. Then get to the mission in the Companions where they give you the Werewolf blood. Have Serana with you before you go into the underforge to drink the blood. Save once you get in the Underforge (in case you mess up). You want to press your Vampire Lord Power button at the same time as you Drink the Werewolf blood. Once you exit the underforge you will need to quickly revert your Vampire Lord form back to Human form and tell Serana to turn you back into a Vampire Lord. BOOM! Hybrid Fussion.\r

I found this glitch on my own so if you would go ahead and give the video a thumbs up.
