It's very difficult to examine the resurrection of Jesus with much sense of empiricism; it was a supernatural miracle only observed by the followers of Jesus, who would have obviously not been impartial. Theirs are the only recorded accounts of the Resurrection (at least that aren't believed to have been tampered with or edited) and they are all from the New Testament, which skeptics argue is unsettlingly convenient. Believers will sometimes argue that the records from the Apostles are satisfactory evidence that the Resurrection happened while others attribute it to the mystery of faith (that the Resurrection wouldn't be a miracle if it were/could be explained).

Either way, as physical evidence of the Resurrection is scant, there isn't much to go on to properly evaluate the event in a historical sense. For better speculations about the Resurrection, I'd ask a philosopher or a Christian theologian (like Vermes, Miethe, or Robert Price), as that's much more their bag. What can be examined historically, though, is what different Christians believe about the Resurrection and how this has impacted their religion on different scales (which is incredibly interesting, in my opinion).

What sort of evidence would you think there could be? We're taking about magic here. You might as well ask, "What empirical evidence exists for Jesus walking on water." How would a historian go about "proving" such a claim?

Look at the saint's lives of Medieval Europe. Historians can use them to learn about their contemporary world, but they make no claims with regard to their magical abilities. The same goes for the Gospels in the hands of historians. They can tell us about life in the first century Levant, but historians aren't in the business of magic.
