Michael Patton has a nice set of posts on the evidence for the resurrection.
Under internal evidence (i.e., confirming features within the biblical texts) he cites the following:
- Honesty
- Irrelevant Details
- Harmony
- Public Extraordinary Claims
- Lack of Motivation for Fabrication
For the external evidence (i.e., support from outside the biblical texts) he cites the following
- Preservation of the Documents
- Archeology
- Extra-biblical Attestation
- Survival in a Hostile Environment
