There is probably a smarter way, but you can add the headers manually like this:

var client = new IdentityProofingService.IdentityProofingWSClient();

using (new OperationContextScope(client.InnerChannel))
{
    OperationContext.Current.OutgoingMessageHeaders.Add(
        new SecurityHeader("UsernameToken-49", "12345/userID", "password123"));
    client.invokeIdentityService(new IdentityProofingRequest());
}

Here, SecurityHeader is a custom implemented class, which needs a few other classes since I chose to use attributes to configure the XML serialization:

public class SecurityHeader : MessageHeader
{
    private readonly UsernameToken _usernameToken;

    public SecurityHeader(string id, string username, string password)
    {
        _usernameToken = new UsernameToken(id, username, password);
    }

    public override string Name
    {
        get { return "Security"; }
    }

    public override string Namespace
    {
        get { return "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"; }
    }

    protected override void OnWriteHeaderContents(XmlDictionaryWriter writer, MessageVersion messageVersion)
    {
        XmlSerializer serializer = new XmlSerializer(typeof(UsernameToken));
        serializer.Serialize(writer, _usernameToken);
    }
}


[XmlRoot(Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd")]
public class UsernameToken
{
    public UsernameToken()
    {
    }

    public UsernameToken(string id, string username, string password)
    {
        Id = id;
        Username = username;
        Password = new Password() {Value = password};
    }

    [XmlAttribute(Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd")]
    public string Id { get; set; }

    [XmlElement]
    public string Username { get; set; }

    [XmlElement]
    public Password Password { get; set; }
}

public class Password
{
    public Password()
    {
        Type = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText";
    }

    [XmlAttribute]
    public string Type { get; set; }

    [XmlText]
    public string Value { get; set; }
}

I have not added the Nonce bit to the UsernameToken XML, but it is very similar to the Password one. The Created element also needs to be added still, but it's a simple [XmlElement].
