If you're only concerned with iOS 5+ there is another way that doesn't involve custom views. With the UIAppearance additions, you can use

UIImage * emptyImage() {
    UIGraphicsBeginImageContext(CGSizeMake(1, 1));
    UIImage * emptyImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return emptyImage;
}

UIBarButtonItem * item = [[UIBarButtonItem alloc] initWith...];
[item setBackgroundImage:emptyImage() forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
self.navigationItem.leftBarButtonItem = item;

and if this is an app-wide style, just do

[[UIBarButtonItem appearance] setBackgroundImage:emptyImage() forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

once in your AppDelegate and you won't even need to fuss with individual instances.

    UIButton *tempButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [tempButton setFrame:CGRectMake(2, 1, 34, 34)]; // your Home Button Image width and height.
    [tempButton addTarget:self action:@selector(btnBackClicked:) forControlEvents:UIControlEventTouchUpInside];
    [tempButton setImage:[UIImage imageNamed:@"icon_home.png"] forState:UIControlStateNormal];
    [tempButton setImage:[UIImage imageNamed:@"icon_home_h.png"] forState:UIControlStateHighlighted];
    [self.navigationItem setLeftBarButtonItem:[[UIBarButtonItem alloc] initWithCustomView:tempButton]];

The in your case UINavigationController is doing some additional styling when managing it's navigationBar and the UIBarButtonItems in it. So setting the style to plain will not behave the same as it does when working with a UIToolbar.

What you need is a custom view, something like...

UIImage *image = [UIImage imageNamed:@"icon_home"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:imageView];
barButtonItem.target = self;
barButtonItem.action = @selector(openMenu);
self.navigationItem.leftBarButtonItem = barButtonItem;

Also, you will probably want target to set to self not self.navigationController.
