I am thinking of writing a AT-command based firmware and low power consumption is one of the important considerations. Will UART still be able to receive data when ESP8266 is in sleep mode? I would like to keep ESP8266 asleep most of the time to keep power consumption low.

You will have to add an interupt somewhere . See Arduino.cc interupts.
