I watched Hiroshima: The Next Day on SBS last night. It was very interesting and had some actual science in it. But, I am wondering what the mushroom cloud consists of. Is it mostly water vapour?

In a nuclear one, water vapour and debris. In a volcanic one, ash and water vapour. All driven by a rapidly expanding bubble of hot air.
