I am not quite sure what it is you are trying to do, but unless you want to get additional information from the MCParticle, a SimTrackerHit does not have enough information to uniquely determine a helix.
The Track interface in org.lcsim.event has facilities to get Helix parameters from a given momentum at a point in space, when charge and B Field are known, so you probably find what you are looking for in there.
