The most basic approach would be
myLayer = iface.activeLayer()

Thank you for the response! However I did try that and I got 'name "iface" is undefined' so it doesn't compile - do you know why?– swoodersFeb 16, 2015 at 21:55

Which QGIS version are you using? The code provided by @underdark should work (I use QGIS 2.2 and 2.6 and worked for both). To be extra safe, you could first try
import qgis.utilsand thenmyLayer = qgis.utils.iface.activeLayer()– JosephFeb 17, 2015 at 10:39 -
