Narrative: Shortly after takeoff we experienced and ECAM master caution for an ENG 1 BLEED AIR FAULT. The Captain (pilot not flying) performed the ECAM actions and applicable OEB from the QRH and cleared the caution. Immediately after; another ECAM master caution appeared for a HYD YELLOW SYS RSV OVERHEAT. The Captain again performed the ECAM actions as directed by the flying pilot and cleared the caution. The aircraft status resulting from both ECAMS showed several items inoperative for the flight; including some spoilers; yaw damper; nose wheel steering; and engine bleed 1. Considering the inoperative systems; flight duration remaining; and possible further degradation of the aircraft systems; the Captain contacted Dispatch and Maintenance to discuss a possible air return. After discussing the aircraft status via air cell; the Captain; with cockpit crew agreement; made the decision to return and land overweight with concurrence from Dispatch and Maintenance. The flight crew notified ATC of their intentions to return and declared an emergency as a precaution due to our degraded status. The in-flight crew was briefed and the passengers were informed of our return. Flight was cleared to a holding point and began preparing for an overweight landing (157;000 LBS) on with a tow off by ground personnel. The First Officer (pilot flying) continued flying the aircraft and talking to ATC while the Captain reviewed landing performance data with the inoperative spoilers and overweight procedures in the QRH. With mutual agreement on sufficient landing distance by the First Officer and Dispatch; flight began approach preparations for a Captain flown ILS. The prevailing winds were from the south at 190/23 gust 33 with approaches being conducted to crossing runways. All applicable checklists were performed and the aircraft was cleared for approach and landed without incident. The aircraft came to a stop on the Runway and was met by a company tug crew and emergency equipment. The aircraft was towed clear of the runway and into the gate. Upon securing the aircraft; logbook entries were made for the engine bleed; HYD RSV overheat; and overweight landing. The aircraft was deplaned and passengers/crew reassigned to a standby aircraft.

Synopsis: Immediately after takeoff an A320 ECAM alerted ENG 1 BLEED AIR FAULT; then YELLOW SYS RSV OVERHEAT so an emergency was declared and the aircraft returned to the departure airport.
