Wikipedia actually has some pretty good pseudocode for depth-first traversal. These traversal algorithms label all the nodes in the graph with the order they appear in a traversal. You instead want to immediately return the path to the goal when the goal is found.

"Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking. Extra memory, usually a stack, is needed to keep track of the nodes discovered so far along a specified branch … " - Dfs stack algorithm
