Go to the Oracle tab in the game and select "chest". Select the chest you wish to roll and on the main page there should be a link to use your free roll.

What you mean by no outcome from daily pray? Daily prayer add points to Health/Defense/Stamina/Attack/Energy depending on which demi god you pray to.

As for lumber and iron, you get that from hitting people in Conquest, or from daily collections if your guild has lands to collect from.

Maybe you have already earned all the prizes from praying to that/those demigod/s and now you "only" get the increase on the related stat.
You can go to Oracle // Demi-Power tab, then select the demi-god you are praying to and click in "View rewards" to see if you are done or not.

Regarding Iron-Lumber, apart from Mursilis' answer, you can usually* purchase them in the Mystic Emporium (Main page or Oracle // Mystical tab).
*: I get any of them offered at least 4-5 times a week, but you know what happens when you need something...
