The fastest and laziest way of gerrymandering is by strictly using party affiliation. One can correlate party affiliation with race/gender/household income/county tax rates. At the state level, all this information is available online to anyone so you may not get an exact number on party affiliation, you can make a very accurate estimate and use that data to draw district lines. For a true non-gerrymandered district lines, you only need the population and make sure there's not a single gap between the districts.
