Future Vegeta's life was exactly the same as his main timeline counterpart's life until August of Age 764 when Future Son Goku used the Instant Transmission to arrive on Earth and kill Future Frieza and Future King Cold. Sometime afterward, Vegeta trained and became a Super Saiyan.
In Age 766, Future Goku had been stricken down by a deadly Heart Virus that had no cure. Future Vegeta, along with the other Z Fighters and company await the news of Future Goku's health. However, Future Goku passes away, leaving Future Vegeta shocked about Future Goku's death and finds himself very upset due to the fact that he will never get his chance to defeat his rival in battle.
Six months later on May 12th, Age 767, the Androids attack and Future Vegeta is the second Z Fighter to be killed by them. In the TV special, Vegeta is shown receiving a hard kick to the stomach by Future Android 17, and in the episode "Ghosts from Tomorrow" it is shown during a flashback that he dies after being struck by 17's Photon Flash while stuck in the ground after receiving a brutal attack. In both instances, he retains his Super Saiyan power and abilities. Future Vegeta was 35 years old when he was killed by the Androids.
Like his alternate counterpart, sometime after the battle with Future King Cold and Future Frieza, Future Vegeta manages to transform into a Super Saiyan after undergoing various training.
Super Saiyan 4
While not shown on-screen, Future Vegeta attained this form at some point while in the Other World according to one of the scenarios in Dragon Ball Z: Budokai Tenkaichi. Future Vegeta used the form to fuse with Future Goku and form Super Saiyan 4 Gogeta.
Future Vegeta fuses with Future Goku to form Super Saiyan 4 Gogeta and face Future Trunks during his and Vegeta's one day on Earth in one of the scenarios in Budokai Tenkaichi.
Dragon Ball Super
Despite not appearing in this series, his spirit was destroyed when Future Zen-Oh wiped out all existence to end Fusion Zamasu's reign of terror. His spirit still continues to exist in the new timeline Whis created, but cannot be revived because the Earth's Dragon Balls are still inert due to Future Piccolo's death. However, it is possible for Future Trunks to revive his fallen friends with the Super Dragon Balls, but he never does so, because both Future Trunks and his mother never knew of the existence of those Dragon Balls, so she never invented a new Dragon Radar. Alternatively if New Namek and the Namekians still exist in the new timeline created by Whis, then they could use the Namekian Dragon Balls which the Future Namekians would surely allow. Another possibility is they could have Future Dende restore the Earth's Dragon Balls like in the main timeline, however both of these scenarios would require Future Bulma and Future Trunks to travel to New Namek.
