You need to flash the code on the Tiny85 using SPI with your Uno as programmer. The actual physical DIP pin numbers on the Tiny are different than the logical pin numbers you use in programming the chip, as you probably already know. I will use the logical pin numbers here. You probably have a pinout diagram of the Tiny85 to determine which physical pins to connect.
Tiny 2 (physical pin 7) to Uno 13 (SCK)
Tiny 1 (physical pin 6) to Uno 12 (MISO)
Tiny 0 (physical pin 5) to Uno 11 (MOSI)
Tiny Reset (physical pin 1) to Uno 10 (SS)
Connect Vcc (to Tiny physical pin 8 ) and Gnd (to Tiny physical pin 4)
upload the ArduinoISP sketch onto the Uno (probably in File | Examples)
Put a capacitor between Uno reset and Gnd. I use 10uf but you can use less.
You can now close the ArduinoISP sketch and get your Tiny85 code into the IDE.
Put an led in series with a current limiting resistor between Uno pin 9 and Gnd (this led is a Heartbeat signal that confirms ArduinoISP sketch is running)
Select Tiny85 from Tools | Board menu
Select Arduino as ISP from the Tools | Programmer menu
Select "Upload using Programmer" from the Files menu. (do not use "Upload")
That is all there is to it...
