Sumit, There are a lot of NAD83 UTM projection zones. You need to chose the proper one. Without learning a fair amount about datums, projections, and the area where you are working, you may be best looking on wikipedia and spatial reference to guess a UTM zone that matches your general area. NAD83 is the North American Datum of 1983, you may want a different datum for your area. A rough guess that may be a decent starting place might be WGS84 UTM 45N.
Datums, projections, etc are incredibly complex. USGS gives an overview here, http://egsc.usgs.gov/isb/pubs/MapProjections/projections.html I don't have any advice for any easy or quick way to select a proper datum and projection. If you know someone working with similar data in the same area, ask them. You may be best leaving the data in EPSG:4326, I don't know.
