Use MNodeMessage.addAttributeChangedCallback
id = OpenMaya.MNodeMessage.addAttributeChangedCallback(node, func,
clientData)
create a callback method (that you pass as to func above) like
def attributeChangedCallback(self, msg, mplug, otherMplug,
clientData):
nodeName, attrName = mplug.name().split('.')
if msg & OpenMaya.MNodeMessage.kAttributeRemoved:
print 'attr %s on node %s was removed' % (attrName, nodeName)
