My processing varies depending on what I have taken but I tend to make the decision as to how I will edit in the field. Any composition with a high range of brightness gets HDR treatment, where bracketed shots are taken to capture the whole spectrum, then combined using HDR Merge in Lightroom, then reimported. With these, and single exposures, I then adjust clarity / vibrance / shadows / highlights / temp / chom. aberration reduced / spots corrected, straightened then exported. It's important that you get the exposure right in camera, as you will find noise is introduced when brightening dark areas of an image.
This may be over the top for some peoples tastes, however I think taking time in post can really enhance your images.
