The first thing we would need to do is increase the planetary temperature. This could be accomplished with the construction of giant orbital mirrors focused on the poles. The focused sunlight would melt the trapped dry ice, thickening the atmosphere by several tens of thousands of pascals. The atmospheric pressure would likely be too low for humans to endure, but it would definitely be thick enough for liquid water to exist. With the thicker atmosphere and subsequent higher temperatures, the ice trapped at the poles would melt, likely covering the majority of the northern hemisphere in a vast ocean.
We could then introduce cyanobacteria to convert the atmospheric carbon dioxide into oxygen, and eventually nitrogen fixing organisms to convert ammonia into nitrogen. We would likely need to add additional nitrogen to the atmosphere, which could be accomplished with atmospheric chemical engineering. We could also mine nitrogen from the Venusian atmosphere. Venus only has 3.5% atmospheric nitrogen, but the atmosphere in so thick there is over right times as much nitrogen in the Venusian atmosphere as that of Earth.
