How to add components to all spawned prefabs ?

This is script is attached to a prefab that is spawned two times. But awake or start works only for one object. How can I run this code for both, when object is spawned.

void Awake () {

     gameMenu = GameObject.Find("GameMenu").GetComponent<GameMenu>();
     mainMenu = GameObject.Find ("MainMenu").GetComponent<MainMenu> ();
     score1 = GameObject.Find ("Score1");
     score2 = GameObject.Find ("Score2");
     deckController = GameObject.Find("GameMenu").GetComponent<DeckController2>();

     Dice = GetComponent<DiceController>();
     Dice.Dices [0] = GameObject.Find("Dice1");
     Dice.Dices [1] = GameObject.Find("Dice2");
     Dice.Dices [2] = GameObject.Find("Dice3");
     Dice.Dices [3] = GameObject.Find("Dice4");
     Dice.Dices [4] = GameObject.Find("Dice5");
     Deck = deckController;

     currentVariant = (int)Buttons.none;
     currentState = (int)States.waiting;

     mainMenu.gameObject.SetActive(true);
     gameMenu.gameObject.SetActive(false);
 }
