I got my iPad yesterday, once synced all iPhone apps synced to iPad. Some of the apps “auto” adjusted to the iPad format while other where in iPhone format. How does that technically work? Or rephrase: How do I as app developer deploy both iPad och iPhone at once for both formats with that “auto” behavior?

Each application has a deployment target, which describes on what devices it can be launched. “Adjusted” apps list both iPhone and iPad as their target. In this case application includes icons, images and views for both iPhone and iPad, and the internal logic detects which view should be used depending on the device type.
There is a tutorial on how to make your apps iPad-compatible.
